Sarah Palin ended her debate performance last Thursday with a slightly garbled quote from Ronald Reagan about how, if we aren’t vigilant, we’ll end up “telling our children and our children’s children” about the days when America was free. It was a revealing choice.

You see, when Reagan said this he wasn’t warning about Soviet aggression. He was warning against legislation that would guarantee health care for older Americans — the program now known as Medicare.

Conservative Republicans still hate Medicare, and would kill it if they could — in fact, they tried to gut it during the Clinton years (that’s what the 1995 shutdown of the government was all about). But so far they haven’t been able to pull that off.

So John McCain wants to destroy the health insurance of nonelderly Americans instead.
